How to Automate OG Images with D2 and Bash Script

Read how I moved from third‑party free tools (like OG Image Maker) to D2, a text‑to‑diagram language, for local, customizable OG image generation. Combining D2 with a Bash script helped automate the process and produce ready‑to‑use OG images. The workflow uses CLI image tools (pngquant, cwebp, ImageMagick) and I talk about the benefits of text‑based templates, offline generation, and automation.
